I´ve estimated a model with the poLCA-package in R and want to save the starting values to a file, so I can re-estimate exactly the same model anytime.
This is a list of starting values for one model:
List of 8
$ : num [1:2, 1:6] 0.219 0.193 0.16 0.193 0.184 ...
$ : num [1:2, 1:6] 0.0731 0.2054 0.228 0.144 0.2028 ...
$ : num [1:2, 1:6] 0.0396 0.0965 0.0286 0.1494 0.1609 ...
$ : num [1:2, 1:6] 0.20998 0.173634 0.105792 0.000588 0.06236 ...
$ : num [1:2, 1:6] 0.163 0.19 0.167 0.178 0.246 ...
$ : num [1:2, 1:6] 0.1602 0.1438 0.1963 0.0848 0.2218 ...
$ : num [1:2, 1:6] 0.0298 0.3022 0.2179 0.094 0.0228 ...
$ : num [1:2, 1:6] 0.0167 0.2444 0.3257 0.1298 0.3652 ...
And these are all its values:

First I thought, that I can convert the list to a dataframe and save it as a .csv-file. But I don't know, how I would read-in this file to have exactly the same list, that I get from the model.
I already looked around stackoverflow, but didn´t find the answer to my question. I don't mind if the file would be .csv, .txt or if it´s one file or many. I am sorry, if I can't offer any more ideas or code for my question. I don't know where to start.
saveRDS(starting.values, file="fname.RData")
?saveRDS
Allows you to save one or more R objects to a single file.
Load with
readRDS("fname.RData")
(Edited from comments below, since the previous save and load functions don't seem to work anymore.)
